Light strips are a pain and require components. Atomic nightlights have always been late game for me, they are rare and very hard to make. It is basically a find that allows you to read books into the night with virtually no work or resource consumption. It is a minor and simple item, but on that note cataclysm has thousands of items like that, and that is partially what makes it fun. What other game have you played that has fire bows, matches, lighters and refillable lighters. You can’t convince me that a book light has less of a place in this game than say, a vibrator or a PDA. It doesn’t need to be game changing to be worth making, and since reading by flashlight isn’t really viable I think there is a place for it.
